Used as a silylating agent in organic synthesis, particularly for introducing dimethylsilylmethyl groups into molecules. It is valuable in the preparation of silicon-containing intermediates for pharmaceuticals and agrochemicals. Commonly employed in the modification of polymers and surfaces to enhance hydrophobicity and thermal stability. Also utilized in the production of silicone resins and as a crosslinking agent in silicone rubber formulations. Its reactivity makes it suitable for functionalizing silica and glass surfaces in analytical chemistry and microelectronics.
